[PATCH] D86335: [RegisterPressure] Use Register instead of unsigned for RegUnit

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec added a comment.

There is one thing I never really understood: is regunit really a register? On our target it is for the fact, but generally speaking? It looks like a quite artificial iterator for me. In particular regunit numerical value does not need to match any real physreg as far as I understand.
